7 This invention =re lat es .to apparatus for use in generating orproducing gas to. be sup phedto internalcombustion engmes and for heating and"for l'ike purposes, and it consists in so constructing said apparatus that the efliciency thereof: is greatly increased v maintenance is comparatively little. V

. ltsilobj ect-is to providetmeans for =distrib;-- uting air evenly across and through space in the generator and insuring a practi cally perfect combustion of the tarry vapors and rendering them innocuous, and also to provide means for insuring that the tarry vapors are driven off before the fuel enters the incandescent zone, and for insuring that a considerable portion of the tarry vapors pass down through the central pipe hereinafter described, and also means for supporting the fuel. It also provides meansfor the removal of spent fuel, ashes, and, other refuse therefrom, without permitting the in-. gross of air into, or the egress of gas out of same during the removal of saidrefuse.

- In the drawings accompanying this specification Figure 1 is a vertical section illustrating the invention. Fig. .2 is a planthereofp Fig. 3 is a section through the top of the generator at right angles i'to the section shown in Fig. 1.

-Acoordi1ig to the invention the generator (1) is of substantially oblong section, that admit air within the pipe. In the case where V the roof is not used no air ports are required. It has a large outlet (,5) at its lower end which allows air to pass through it at a low "*G srR Q the fuel;

which prevents air entering the bottom of the generator and mixing with the gas. Anyashes that fall through the grate pass down through the ashlutes (21) into the water seal. The grate (8) being of the shape shown forms a larger area than the usual fiat grate facilitating the passage of gas out through between the bars (11). 'Thedisrtillation zone (17), the combustion zone (18), the decomposition zone (19), and the their respective positions. The other portions of the apparatus are the'same as heretofore. r

The invention is operated, as follows:

top (12) of the-generator. (1) if'a down ash zone (20) are shown approximately in Air or air and steam is admitted at the draft onlyis used, and at the top- (12) and, c

bustion. In the process of this combustion the tar is driven off in the form of vapor from the fuel at the top (14) of the fuel space (15) in thegenerator (1). and is drawn or driven through thebed (16) "or incandescent fuel beneath. The tarry va pors meet in this incandescentfuel with a supply of air or air and steamwhich is supplied through the special pipe (2) above if a combined 'up down .draftisused; this'air is to support com described at the depth above referred to V l which insures the combustion ofthese tarry vapors and renders them innocuous.

The tarry vapors are partially driven off upward under the slight pressure due to the heat in the combustion zone and mingle with the'air and pass down with it through the pipe (2) above described, as this is the path of least resistance, thus insuring thorough mixing before entering the incandescent zone and causing a very efficient combustion. The tarry vapors that do not pass through this central air pipe (2) pass down with air outside the pipe (2) into the incandescent zone and are there consumed.

Having now described my said invention, what I claim as new and desire to secure by Letters Patent is l. A gas producer comprising a generator body, an air supply pipe freely suspended within the body from diametrically opposite sides thereof only topermit expansion there of in any direction.

2. A gas producer comprising a generator body rectangular in cross section, an air distributing member rectangular in cross section, and means for suspending said member centrally within the body from diametrically opposite sides thereof only to permit expansion thereof in any direction.

3. As an article of manufacture, an air distributer for gas generators comprising a Copies of this patent may be obtained for body portion rectangular in cross section and open at its lower end, an inverted V- shaped roof for the upper end thereof, said roof being provided with a plurality of air admission openings in the inclined portions thereof, and means for freely suspending said distributer in operative position.

4. As an article of manufacture, an air distributerfor gas generators comprising a body portion open at its lower end, an inverted V-shaped roof for the upper end thereof, said roof being provided with a plurality of air admission openings in the inclined portions thereof, and means proj ecting from diametrically opposite sides of the distributer for freely suspending the same in operative position. 3

In testimony whereof I have afiixed my signature in presence of two witnesses.
